Solid state amps are usually more prone to damage by excessive output current, so you don't want to short the outputs or drive a load that has too low impedance. Tube amps sometimes are just the opposite, in that too high impedance load will allow the plate voltage swings to become excessive. This isn't the case with all tube amps, but it is something to consider. When in doubt, ask the manufacturer of the amp.
